67b5f33d46 [general] Remove the last bits of gnu-efi
With the new bootloader changes that use clang to directly build an EFI
application, the last piece of GNU-EFI that was used (the linker script)
is no longer necessary.

Thanks for being a great starting point, GNU-EFI!

b675dfd014 [boot] Fix header include path for uefi headers
After the previous commit, the header path was different. This updates
the build scripts to point to the right location.

fc2b884af9 [build] Copy uefi headers into project
Eventually the UEFI headers should be brought in from their own project,
but for now, like the other projects under external/, these are being
copied into this repository.

cbd19fa070 [kernel] Don't use deferred logging for now
The last bug getting back to par with master - looks like there might be
threading issues with the logger task at the moment. Turning it off for
now.

83b330bf2b [kernel] Use constants for known pml4e indices
There were a few lingering bugs due to places where 510/511 were
hard-coded as the kernel-space PML4 entries. These are now constants
defined in kernel_memory.h instead.

cc9cde9bfe [tooling] Remove old GDB workarounds
GDB works far better now with QEMU's `-S` flag. No longer does it
complain about changing the target from 32 to 64 bits. Get rid of the
old `waiting` loop and `sleep` call in the GDB config for the kernel.

774f6fc334 [kutil] Don't use delete on non-new pointers
`kutil::vector` was calling `operator delete []` on memory that had not
been allocated with `operator new []`, and so was deleting the wrong

35b1d37df0 [memory] Rework memory_initialize for new loader
Created a new `memory_initialize()` function that uses the new-style
kernel args structure from the new bootloader.

Additionally:
* Fixed a hard-coded interrupt EOI address that didn't work with new
  memory locations
* Make the `page_manager::fault_handler()` automatically grant pages
  in the kernel heap

75641a4394 [boot] Add explicit memory map pointer to args
The bootloader was previously just passing the memory map as a module,

e1d148a34d [boot] Fix a bug with address-index translation

index, and so on).

* When using the non-allocating version of `get_uefi_mappings` the
  length was not getting set. Reworked this function.
* Having `build_kernel_mem_map` from `bootloader_main_uefi` caused it to
  get an out of date map key. Moved this function into `efi_main` right
  before exiting boot services.

66ca3a3f9b [boot] Consolidate mapping code into iterator obj
The page table code had been copied mostly verbatim from the kernel, and
was a dense mess. I abstraced the `page_table_indices` class and the old
loop behavior of `map_in` into a new `page_entry_iterator` class, making
both `map_pages` and the initial offset mapping code much cleaner.

4f4a35a7be [boot] Set up initial page tables
Set up initial page tables for both the offset-mapped area and the
loaded kernel code and data.

* Got rid of the `loaded_elf` struct - the loader now runs after the
  initial PML4 is created and maps the ELF sections itself.
* Copied in the `page_table` and `page_table_indices` from the kernel,
  still need to clean this up and extract it into shared code.
* Added `page_table_cache` to the kernel args to pass along free pages
  that can be used for initial page tables.

42dfa6ccfe [boot] Only allocate memory map once
The `build_kernel_mem_map` function now calls `get_uefi_mappings`
itself, instead of having the efi map passed in. `get_uefi_mappings`
also now takes a `bool allocate` to direct it to actually allocate
the map or not. If it doesn't, it instead just returns the size of
the map and the metadata - which `build_kernel_mem_map`	uses to decide
how much space to first allocate for the kernel's map.

a6e4995963 [boot] Fix call to exit_boot_services
Exiting boot services can't actually be done from inside
`bootloader_uefi_main`, because there are objects in that scope that run
code requiring boot services in their destructors.

Also added `support.cpp` with `memcpy` because clang will emit
references to `memcpy` even in freestanding mode.

Added a `debug_break` function to allow for faking breakpoints when
connecting to the bootloader with GDB.

6302e8b73a Overhaul memory allocation model
This commit makes several fundamental changes to memory handling:

- the frame allocator is now only an allocator for free frames, and does
  not track used frames.
- the frame allocator now stores its free list inside the free frames
  themselves, as a hybrid stack/span model.
  - This has the implication that all frames must currently fit within
    the offset area.
- kutil has a new allocator interface, which is the only allowed way for
  any code outside of src/kernel to allocate. Code under src/kernel
  _may_ use new/delete, but should prefer the allocator interface.
- the heap manager has become heap_allocator, which is merely an
  implementation of kutil::allocator which doles out sections of a given
  address range.
- the heap manager now only writes block headers when necessary,
  avoiding page faults until they're actually needed
- page_manager now has a page fault handler, which checks with the
  address_manager to see if the address is known, and provides a frame
  mapping if it is, allowing heap manager to work with its entire
  address size from the start. (Currently 32GiB.)

Additionally, there were several bug fixes needed to allow this:
- frame_allocator was allocating its frame_blocks from the heap, causing
  a circular dependency. Now it gives itself a page on its own when
  needed.
- frame_allocator::free was putting any trailing pages in a block back
  into the list after the current block, so they would be the next block
  iterated to.
- frame_allocator::free was updating the address it was looking for
  after freeing some pages, but not the count it was looking for, so it
  would eventually free all pages after the initial address.

67b9f45004 Offset-map the entire offset region with 1G pages
Instead of building nested page tables for the offset region, just
offset map the entire thing into kernel memory with one PDP mapping
1GiB large pages. This is more efficient and avoids the "need a
page table to map in a page table" dependency loop.

2035fffa1c Fix loading large process images.
2MiB large pages were being used for any large page mapping, but the

allow them for offset pointers (eg MMIO space) that will never be
unmapped.

194527e0fe Fix address-marking bugs
* Non-blocksize-aligned regions could fail to be found. Have the
  bootloader load them aligned.
* Consolidating used frame blocks in the bootstrap means these would
  have been impossible to free as address space
* mark_permanent wasn't actually removing blocks from the free list

8cdc39fdee Switch page_manager to use frame_allocator.
Removed the frame allocation logic from page_manager and replaced it
with using an instance of frame_allocator instead. This had several
major ripple effects:

- memory_initalize() had to change to support this new world
  - Where to map used blocks is now passed as a flag, since blocks don't
    track their virtual address anymore
  - Instead of the complicated "find N contiguous pages that can be
    mapped in with one page table", we now just have the bootloader give
    us some (currently 64) pages to use both for tables and scratch
    space.
  - frame_allocator initialization was split into two steps to allow
    mapping used blocks before std::move()ing them over

62c559043d Pause syscall and int 0xee interrupt syscalls
The syscall/sysret instructions don't swap stacks. This was bad but
passable until syscalls caused the scheduler to run, and scheduling a
task that paused due to interrupt.

Adding a new (hopefully temporary) syscall interrupt `int 0xee` to allow
me to test syscalls without stack issues before I tackle the
syscall/sysret issue.

Also implemented a basic `pause` syscall that causes the calling process
to become unready. Because nothing can wake a process yet, it never
returns.

The scheduler's create_process now sets up the stack to iretq into a

#### 2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
### 3. Responsibilities
#### 3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under the
terms of this License. You must inform recipients that the Source Code Form of
the Covered Software is governed by the terms of this License, and how they can
obtain a copy of this License. You may not attempt to alter or restrict the
recipients' rights in the Source Code Form.
#### 3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
* **(a)** such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of the
Executable Form how they can obtain a copy of such Source Code Form by
reasonable means in a timely manner, at a charge no more than the cost of
distribution to the recipient; and
* **(b)** You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the license
for the Executable Form does not attempt to limit or alter the recipients'
rights in the Source Code Form under this License.
#### 3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for the
Covered Software. If the Larger Work is a combination of Covered Software with
a work governed by one or more Secondary Licenses, and the Covered Software is
not Incompatible With Secondary Licenses, this License permits You to
additionally distribute such Covered Software under the terms of such Secondary
License(s), so that the recipient of the Larger Work may, at their option,
further distribute the Covered Software under the terms of either this License
or such Secondary License(s).
#### 3.4. Notices
You may not remove or alter the substance of any license notices (including
copyright notices, patent notices, disclaimers of warranty, or limitations of
liability) contained within the Source Code Form of the Covered Software,
except that You may alter any license notices to the extent required to remedy
known factual inaccuracies.
#### 3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support, indemnity
or liability obligations to one or more recipients of Covered Software.
However, You may do so only on Your own behalf, and not on behalf of any
Contributor. You must make it absolutely clear that any such warranty, support,
indemnity, or liability obligation is offered by You alone, and You hereby
agree to indemnify every Contributor for any liability incurred by such
Contributor as a result of warranty, support, indemnity or liability terms You
offer. You may include additional disclaimers of warranty and limitations of
liability specific to any jurisdiction.
### 4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute, judicial
order, or regulation then You must: **(a)** comply with the terms of this
License to the maximum extent possible; and **(b)** describe the limitations
and the code they affect. Such description must be placed in a text file
included with all distributions of the Covered Software under this License.
Except to the extent prohibited by statute or regulation, such description must
be sufficiently detailed for a recipient of ordinary skill to be able to
understand it.
### 5. Termination
**5.1.** The rights granted under this License will terminate automatically if
You fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor are
reinstated **(a)** provisionally, unless and until such Contributor explicitly
and finally terminates Your grants, and **(b)** on an ongoing basis, if such
Contributor fails to notify You of the non-compliance by some reasonable means
prior to 60 days after You have come back into compliance. Moreover, Your
grants from a particular Contributor are reinstated on an ongoing basis if such
Contributor notifies You of the non-compliance by some reasonable means, this
is the first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after Your
receipt of the notice.
**5.2.** If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions, counter-claims, and
cross-claims) alleging that a Contributor Version directly or indirectly
infringes any patent, then the rights granted to You by any and all
Contributors for the Covered Software under Section 2.1 of this License shall
terminate.
**5.3.** In the event of termination under Sections 5.1 or 5.2 above, all end
user license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
### 6. Disclaimer of Warranty
> Covered Software is provided under this License on an "as is" basis, without
> warranty of any kind, either expressed, implied, or statutory, including,
> without limitation, warranties that the Covered Software is free of defects,
> merchantable, fit for a particular purpose or non-infringing. The entire risk
> as to the quality and performance of the Covered Software is with You.
> Should any Covered Software prove defective in any respect, You (not any
> Contributor) assume the cost of any necessary servicing, repair, or
> correction. This disclaimer of warranty constitutes an essential part of this
> License. No use of any Covered Software is authorized under this License
> except under this disclaimer.
### 7. Limitation of Liability
> Under no circumstances and under no legal theory, whether tort (including
> negligence), contract, or otherwise, shall any Contributor, or anyone who
> distributes Covered Software as permitted above, be liable to You for any
> direct, indirect, special, incidental, or consequential damages of any
> character including, without limitation, damages for lost profits, loss of
> goodwill, work stoppage, computer failure or malfunction, or any and all
> other commercial damages or losses, even if such party shall have been
> informed of the possibility of such damages. This limitation of liability
> shall not apply to liability for death or personal injury resulting from such
> party's negligence to the extent applicable law prohibits such limitation.
> Some jurisdictions do not allow the exclusion or limitation of incidental or
> consequential damages, so this exclusion and limitation may not apply to You.
### 8. Litigation
Any litigation relating to this License may be brought only in the courts of a
jurisdiction where the defendant maintains its principal place of business and
such litigation shall be governed by laws of that jurisdiction, without
reference to its conflict-of-law provisions. Nothing in this Section shall
prevent a party's ability to bring cross-claims or counter-claims.
### 9. Miscellaneous
This License represents the complete agreement concerning the subject matter
hereof. If any provision of this License is held to be unenforceable, such
provision shall be reformed only to the extent necessary to make it
enforceable. Any law or regulation which provides that the language of a
contract shall be construed against the drafter shall not be used to construe
this License against a Contributor.
### 10. Versions of the License
#### 10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section 10.3,
no one other than the license steward has the right to modify or publish new
versions of this License. Each version will be given a distinguishing version
number.
#### 10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version of the
License under which You originally received the Covered Software, or under the
terms of any subsequent version published by the license steward.
#### 10.3. Modified Versions
If you create software not governed by this License, and you want to create a
new license for such software, you may create and use a modified version of
this License if you rename the license and remove any references to the name of
the license steward (except to note that such modified license differs from
this License).
#### 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the notice
described in Exhibit B of this License must be attached.

**jsix** is the kernel for the hobby OS that I am currently building. It's
far from finished, or even being usable. Instead, it's a sandbox for me to play
with kernel-level code and explore architectures.
@@ -25,16 +25,54 @@ The design goals of the project are:
temporarily) in some places to allow me to play around with the related
hardware.
A note on the name: This kernel was originally named Popcorn, but I have since
discovered that the Popcorn Linux project is also developing a kernel with that
name, started around the same time as this project. So I've renamed this kernel
jsix (Always styled _jsix_ or `j6`, never capitalized) as an homage to L4, xv6,
and my wonderful wife.
## Building
Popcorn uses the `waf` build tool, which is included in the repo. The other
requirements are:
jsix uses the [Ninja][] build tool, and generates the build files for it with a
custom tool called [Bonnibel][]. Bonnibel can be installed with [Cargo][], or
downloaded as a prebuilt binary from its Github repository.
* python (to run waf)
[Ninja]: https://ninja-build.org
[Bonnibel]: https://github.com/justinian/bonnibel
[Cargo]: https://crates.io/crates/bonnibel
Requrirements:
* bonnibel
* ninja
* clang
* nasm
* mtools
* curl for downloading the toolchain
### Setting up the cross toolchain
Running `pb sync` will download and unpack the toolchain into `sysroot`.
#### Compiling the toolchain yourself
If you have `clang` and `curl` installed, runing the `scripts/build_sysroot.sh`
script will download and build a LLVM toolchain configured for building jsix
host binaries.
### Building and running jsix
Once the toolchain has been set up, running Bonnibel's `pb init` command will
set up the build configuration, and `pb build` will actually run the build. If
you have `qemu-system-x86_64` installed, the `qemu.sh` script will to run jsix
in QEMU `-nographic` mode.
I personally run this either from a real debian amd64 testing/buster machine or
a windows WSL debian testing/buster installation. The following should be
enough to set up such a system to build the kernel:
sudo apt install qemu-system-x86 nasm clang-6.0 mtools curl
sudo update-alternatives /usr/bin/clang clang /usr/bin/clang-6.0 1000
sudo update-alternatives /usr/bin/clang++ clang++ /usr/bin/clang++-6.0 1000
curl -L -o pb https://github.com/justinian/bonnibel/releases/download/2.0.0/pb_linux_amd64 && chmod a+x pb
After cloning, run `waf configure`. Then you can run `waf build` to build the
project, and `waf test` to run the tests. A floppy disk image will be built in
`build/popcorn.img`. If you have `qemu-system-x86_64` installed, then you can
run `waf qemu` to run it in `-nographic` mode.
